I've drawn my own drawings to bend a complete upper reciever section.
My problem is I've bent the steel ,and I have not got each side to line up corectly yet.
The drawing is layed out for the folds in the mag well,an the trunnion
support.You do have more than one bend to make the mag section.
If you have a kit,you can make your own drawings.You do need
a mag,trunnion,feed ramp.(you can make your own feed ramp).Mic your
kit an order some flat steel stock.4130 stock.Aircraft Spruce.com
Up date,Ive made 4 flats sofar.I'm still working on the spring back from the 4130.
Made new jig from angle iron,an turned a new round stock.Will see what happens.
Always accepting input ,thanks AL

Some people are cutting up old Russian Nagant barrels 7.62x54r to make 16" 7.62x25 barrels, if you have a lathe & a few gunsmith tools its possible. Weaponeer has a few ( How I did It ) Forums there. - That info might even be there at Gunco I don't know for sure, wish I could be more help.

Thes guys think that the 9mm has no stopping power.They know that most of the 7.62x25 is machine gun ammo.I don't believe it matters when you put 30+rounds into someone .I personally like the7.25 only because I own other guns of that size.
Thanks AL

Do you really think some 7.62x25 ammo is hotter than others for sub-machine gun use? In the AO, would it be prudent to have two loads, same caliber, that can only be used a) in a pistol or b) in a sub-machine gune?

A supply nightmare. The 7.62X25 "hot" sub-machine gun ammo is a myth.
